What to do with Icon? WWYD??

Is there any use hanging onto olympia's icon (already have her) if there's no other decent swap in Mystic? Already have the angels and have no interest in white bishop. any chance whether they will offer starstone swaps for her again? they seem to be locked into dropping the availability of such as soon as they come out with the next of this type of angel. (which doesn't seem too often). Are they doing away with new angels entirely???
